Bio

I am a third-year Ph.D. candidate in the Department of Electrical and Computer Engineering, UCLA. I am fortunate to work with Prof. Abeer Alwan on problems of speech processing. For my current work, I am focusing on children's speech recognition in a low-resource perspective and end-to-end speech recognition. Prior to that, I received my Master's and Bachelor's degree from Beijing University of Posts and Telecommunications (BUPT) in 2019 and 2016, respectively.
